I am a postdoc in the group of Beatrice Pozzetti.

Previously, I completed my PhD in Bonn under the supervision of Ursula Hamenstädt.

Here is my CV.

I co-organize, with Beatrice Pozzetti, Mitul Islam, and James Farre, the Heidelberg Differential Geometry Seminar.

Research interests: I usually work on problems involving geometric structures on surfaces and 3-manifolds.
I have a special interest for hyperbolic geometry, so my motivation often comes from the connections with one of the following topics:

Hyperbolic surfaces and hyperbolic 3-manifolds
Kleinian groups
(Higher) Teichmüller theory
